Goronyosaurus nigeriensis Mosasaur Fossil

Here is a picture of a reconstructed skull of a Goronyosaurus nigeriensis (Swinton et al., 1930) fossil at Museo di Geologia e Paleontologia Florence Italy (Università degli Studi di Firenze) in August 2024.  The creature lived during the Upper Cretaceous Period. It might have been found in Sokoto District, Nigeria Africa.

How to Be a Computer Generated Mosasaur

In January 2014, I wrote about How To Be A Megalodon Shark which was about a character in a very popular smartphone game Hungry Shark Evolution. In that posting, I was hoping they would create an arthrodire or mosasaur creature for the game. It was great when they created a Dunkleosteus in late 2014. Now they have created a Mosasaurus creature for the game. It takes quite a bit of virtual gold coins to get this animal and I still have some playing to do in order to get it. Here are some screen shots of the creature preview in the game. I look forward to playing it as it is smaller than the other two characters thus can navigate the underwater caverns better in the game.

This game is mixing modern fish and sharks with fossil sharks and marine reptiles: mosaurus (Mesozoic  Era - Cretaceous Period) Megalodon (Cenozoic Era - Neogene Period) and the Dunkleosteus (Paleozoic Era - Devonian Period).

Possible future additions to the creature library for this game could be the Mesozoic ichthyosaur. Since this is a game developed in England the Temnodontosaurus found by Joseph and Mary Anning in 1811-12 in Lyme Regis could be a good choice.

South Dakota Mosasaur Fossil Tooth?

My cousin has been extracting fossils from a piece of Carlile Shale Formation matrix. It was found in Grant County, South Dakota, USA. He has been slowly breaking it down to reveal the hidden fossil teeth.  The fossils date to the Cretaceous Period (Turonian). The picture shows what might be a mosasaur fossil tooth. Each scale division is a mm.

Thanks to Kenny for the images.

Mosasaurus Teeth from Morocco

Here is a picture of a Mosasaurus fossil teeth set at the Museo di Paleontologia at Sapienza University of Rome Italy. Creatures like this existed in the upper Cretaceous Period. Fossil was found in Khouribya, Morocco.

Mosasaur Fossils

Mosasaur fossils on display at the Muséum national d'histoire naturelle in Paris, France. Learn more at the mosasaur entry at Wikipedia.

UPDATE: Mosasaur fossils on display at the Smithsonian National Museum of Natural History in 2010. The skull fossil is a Clidastes liodontus and the full fossil is Tylosaurus proriger both from Kansas of the Late Cretaceous (80-70 mya).
